47 Flammable Gas Sensor

Key Technical Features:

• High-Sensitivity Gas Sensing: Equipped with a stable, industrial-grade sensor capable of detecting even low-level gas leaks long before they reach explosive concentrations.

• Acousto-Optic Alarm: Features a powerful built-in siren (≥70dB) and a flashing red LED indicator for immediate local warning.

• ZigBee 3.0 Wireless Integration: Sends real-time data and alarm signals to the Wulian Gateway, ensuring your phone receives an alert anywhere in the world.

• Self-Check & Auto-Calibration: Periodically performs internal diagnostics to ensure the sensor remains accurate and functional, with results viewable in the app.

• Interconnected Alarm Logic: Can be programmed to trigger other ZigBee devices in the home simultaneously (e.g., all sirens sounding throughout a villa).

Smart Benefits:

• Automatic Gas Shut-off (Linkage): When a leak is detected, the sensor can automatically command a Wulian 62/63 Valve Closer to shut off the main gas valve instantly, preventing a disaster.

• Ventilation Automation: Can be linked to a Wulian 61/MT Smart Plug to turn on an exhaust fan immediately upon detection, helping to disperse the gas.

• Remote Emergency Notifications: Receive an urgent push notification on your smartphone, allowing you to take action even if you are away from home or the building is empty.

• Combustion Protection: Ideal for protecting elderly family members who may accidentally leave a stove burner on without a flame.

Technical Specifications:

• Detection Gas: Natural Gas (CH4), LPG (Propane/Butane).

• Communication Protocol: ZigBee 3.0 (IEEE 802.15.4).

• Alarm Concentration: ~7% LEL (Lower Explosive Limit) ± 3%.

• Alarm Volume: ≥ 70dB (at 1 meter).

• Power Supply: 100V–240V AC (Standard wall plug or hardwired for continuous monitoring).

• Operating Temperature: -10°C to +55°C.

• Installation: Wall-mounted (Typically 30cm from the ceiling for Natural Gas or 30cm from the floor for LPG).
